Key points from two multi-disciplinary environmental research projects are reported: 1. slowing of ocean currents through the Caribbean and 2. changes in Nile River flow. Both projects cover spatial patterns of climate change evident in past observations and future model projections. In the first project, ocean data assimilation products reveal two places where poleward currents are slowing by retroflection – in the equatorial Atlantic due to northward shift of the Hadley Cell, and in the Gulf Stream near Labrador due to changes in salinity. In the second project, hydrology data assimilation products exhibit rising trends in rainfall, vegetation cover and run-off from the Ethiopian highlands. Model simulations in a ‘greenhouse future’ suggest that diurnal transpiration creates a climate-feedback that underpins water resources. Conclusions offer insights on strategic ways to support ongoing research.
